Abstract

A backup power supply (150) for use with a power plant (100) having a primary power supply (110) that provides primary power to an AC bus (140) for subsequent conversion to DC power includes a battery charger/inverter (155), coupled to the AC bus (140) and couplable to a battery (160), that operates in a normal mode to convert a portion of the primary power to charge the battery and operates in a battery backup mode to convert DC power from the battery to provide the backup power to the AC bus.
